SKATE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 285,836, dated October2, 1883.

To all whom, it 11i/Ly concern:

Be it known that I, ELIsHA W. Oris, of Chelsea, in the county ofSuffolk, State of Massaclu1setts,have `invented a certain new and usefulImprovement in Skate-Rollers, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame, reference being had to the accompanying drawings, forming a partof this specification, in Which- Figure l is an isometrical perspectiveview of my improved roller; Fig. 2, a side elevation of the same; Fig.8, an edge view; Fig. 4, a vertical transverse section; and Figs. 5andlG, sectional views, showing modifications of the improvement.`

. Like letters of reference indicate corresponding parts in thedifferent iigures of the drawings.

My invention relates to that class of rollers which are employed in themanufacture of roller or parlor skates; and it consists in a novelconstruction and arrangement of parts, as hereinafter more fully setforth and claimed, by which a more `effective article of this characteris produced than is nowin ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation, itsextreme simplicity rendering an elaborate description unnecessary.

In the drawings, A `represents the body of the roller7 B the tire, and Cthe cushion.

The body is preferably composed of wood, and is constructed in twocorresponding sec: tions or halves, m m, which have'their peripheriesinwardly beveled or cham fered, as shown at a' w, and are connected bythe transverselyarranged bolts d and nuts f.

Fitted into the groove formed by the bcvels x around the body' of theroller there is a band or cushion, C, composed of elastic rubber, andprovided on its face with the annular groove z' for receiving the tireB.

The tire is iiat, and may be composed of iron, steel, brass, or anyother suitable material, being slightly thicker than the depth of thegroove i, in which it rests, and preferably` about two-thirds as wide asthe cushion C, the

Application filed July 20,1883. (1Y0 model.)

face of which, at all points, is in the axial line of the roller.

,In constructing the roller the tire B is first inserted in thegroove/13 of the cushion C, after which the sections ni m, forming thebody A, are placed on the opposite sides of the cushion, with theirbeveled edges inward, and secured by means of the bolts and nuts d f, ina manner which will be readily obvious without a more explicitdescription. The inner faces of the sections m are removed, or thesections constructed of such a thickness that a space, Z, is leftbetween them to enable a strain to be obtained on the tire by forcingthe cushion C outwardly as the nuts are turned in, the beveled edges :tacting against the corresponding inclines or bevels on the under side ofthe cushion to press the same diagonally against the under side of thetire, and also to elevate the extreme outer edges, n, of the cushion,

thereby tightening the tire, and also furnishing a iirm bearing for theedges and compensating for their wear. The roller is provided with ahole, D,'for receiving an ordinary axlepin, and is designed to bear onthe tire B, but in turning, and also in performing fancy skating, whenthe body of the roller is inclined, the edges t are brought to bear, andthe skater thereby prevented from slipping.

It will be obvious that the rubber cushion will act as a spring toreceive and absorb the jar caused by the roller passing over anyinequalities in the iioor, also, that when the edges becomebadly worn alnew cushion may be readily substituted.

I do not confine myself to the use of the bolts and nuts for securingthe sections of the body, as other means may be employed for thatpurpose; neither do I coniine myself to the special form of the cushionC or the bevels as these may be varied considerably with out departingfrom the spiritof my invention.

In Fig. 5 the edges t are constructed independent of the body of thecushion C, the cushion being let into a rabbet or socket, c, formed inthe sections m.

In Fig. 6 the body and edges of the cushion are integral, or formed inone piece, but the outer edges of the sections m are straight, or inparallelisln with the face of the tire B, and a rabbct or socket, n, isformed in the sections to receive the bodyof thel cushion; but as Ipropose to make the modifications of my improvement, as shown in Figs. 5and 6, the subject-matter of other Letters Patent I do not claim thesaine specifically in this application.

Having` thusexplained my invention, what I claim isl. The improvedskateroller herein described, the same consisting1 of the body A,cushion C, tire B, bolts d, and nuts f, constructed, combined, andarranged to operate substantially as set forth.

2. A skate-roller having` a body provided with an annular elasticcushion around its periphery, and a tire'of less Width than the cushiondisposed around the same, in combination with means for forcing thecushion outwardly against the tire and supporting,1 the projecting edgesofthe cushion, substantially as speciled.

vsections m m, having the beveled edges x for receiving` the tire andcushion, and provided With nuts and bolts or means for forcing` thesections inwardly to expand the cushion and tighten the tire,substantially as set forth.
